Any.do, the popular to-do list management application for iOS, has received a huge update to version 2.0, which introduces a new focus on collaboration among teams and families. All of the app’s previous functions still work the way they did in previous versions, so existing users won’t need to re-learn anything, but those who want better support for groups and sharing will find a lot of useful enhancements in this update.

A new chat function allows members of a project to talk with each other, share files from Dropbox, add and remove group members, and more. Shared lists and tasks make it easy to quickly assign work, update the group’s progress, or just add something to a shared grocery list.

A few new features for premium users include custom background colors across the app, support for adding unlimited members to a group (limited to 2 for free users), or unlimited file sizes (where free users are limited to 5 MB). Premium users can also get highly-customizable repeating tasks and location-based reminders.

The Any.do app is free on the App Store. For the next two weeks, premium subscriptions can be purchased in-app for a special rate of $3 for a month or $27 for a year. After that the price returns to normal ($5/month, $45/year).
